摘　　要：在干旱半干旱地区发展果树，水分是影响其成活及正常生长发育的主导因子．该研究采用了集流造林技术使有限的天然降水在时空上被重新分配，提高降水资源的利用率，并为果树的生长发育创造相对适宜的土壤水环境，协调水分与果树生长的关系，从而使苹果树定植成活率提高３９－１ ％ ～１２４－４ ％ ，幼树栽后第３ 年开花株率３０－０ ％ ，第５ 年产量为９ ９９０－０ ～１４ １１２－０ ｋｇ·ｈｍ － ２ ．Wateris one ofthe restrictive factors in developing fruit trees and affecting their survival and normal growing and development in arid and semi arid areas.The application of runoffforestrytechnologyrealized theredistribution ofnaturalprecipitationintimeand space and improvedthe utilization rate of precipitation resources,thereby it provided a more suitable envi ronmentof soil water for the growth and development of fruit trees. The results of the trial showed :the application ofrunoffforestry technology increased the survivalrate of young appletreesby 39 .1 % ～124.4 % ,30.0 % of the young apple trees blossomed in the third year after plantation ,the yield ofthe young appletrees planted was 9990-0 ～141120kg-hm - 2inthefifth year.
